Pick a package, not a vague “full detail”
Interior, exterior, or both should be named. Interior usually means vacuum, surfaces, and glass. Exterior usually means a wash and dry. Paint correction, engine bays, pet hair, and stain removal take longer and belong in the request if you need them.
Tell the Provider the vehicle type. A compact car, a three-row SUV, and a work truck are not the same job. If there is more than one vehicle, book each one or say how many are included.
Where the car will be
Many detailers work in a driveway. They need water access or they bring their own, and they need enough space to open doors. An apartment garage with a time limit, or a street with no hose, should be in the request.
Winter road film and salt are common on Maryland cars after cold months. A maintenance wash and a full decontamination are different. If the paint feels rough or the lower panels are coated, say that so the Provider brings the right wash process.
What detailing Providers should publish
List the packages you actually offer and the vehicles you turn down. If you are mobile, say what you bring and what the Buyer must provide, such as a hose bib or a covered space in bad weather.
Be specific about add-ons: pet hair, child seats, ceramic spray, and headlight haze. A listing that only says “detail” produces requests you then have to re-quote.
